The chmistry behind airbags

You may need to check the table of physical constants and conversions in your chemistry book to find some of the numbers you need. How does this happen. Warnings are posted against using rear-facing car seats in the front seats of vehicles with passenger-side airbags.

Slight addition in your car loan can be your invaluable expenditure. You could fill a balloon with nitrogen, attach it to a test tube and then stick the test tube in the liquid nitrogen.

Chemistry behind airbag deployment. How to demonstrate?

This strategy is already used for other hazardous components of cars, such as lead-battery cases. HN3 is highly toxic, volatile i. The lead from batteries can be re-sold, but currently there is no market value for airbag canisters.

Now we turn to a theoretical model to explain these macroscopic properties in terms of the microscopic behavior of gas molecules.

Chemistry behind airbag deployment. How to demonstrate?

These sensors send an electric signal to the canister that contains the sodium azide and the electric signal detonates a small amount of an igniter compound.

What does the sign of the force calculated in part a imply about the change in velocity of the body. The kinetic theory of gases assumes that gases are ideal i.

How do air bags work?

Undetonated-Airbag Disposal Thus far we have discussed how airbags function to protect us when there is a head-on collision. Monday, 10 March Do you know the chemistry behind airbags.

If you wanted to use a different set of chemical reactions to generate gas for airbags, what characteristics should the reagents have. Any other type of speed distribution rapidly becomes a Maxwell-Boltzmann distribution by collisions of molecules, which transfer energy.

How do air bags work?

Print Advertisement Joseph S. The area that hits the steering wheel is shown in red.

The History of Airbags - Allen Breed

This is accomplished in two ways: This law, known as the law of inertia, is demonstrated in a car collision. Airbags are a type of automobile safety restraint like seatbelts.

They are gas-inflated cushions built into the steering wheel, dashboard, door, roof, or seat of your car that use a crash sensor to trigger a rapid expansion to protect you from the impact of an accident.

Jan 15,  · For my chemistry class, I had to write a feature article about the chemistry behind airbags (pretty fascinating stuff), and now my teacher has dropped the bomb that we must do a presentation that explains what we studied.

I was hoping to do a small (and i mean small) scale demonstration of how. In this article I will discuss the mechanism behind inflation of airbag and the chemistry behind its quick reaction. The aim of an airbag is to slow the passenger's forward motion as evenly as possible in a fraction of a second.

Even 97 Toyota Camry airbags for older model vehicles are available for driver and passenger, with the latter airbag notoriously double the size of the driver's airbag based on the rider's distance from the dashboard. Scientific American is the essential guide to the most awe-inspiring advances in science and technology, explaining how they change our.

That's not the only chemistry involved.

Notice that the other chemical into which sodium azide falls apart is Na, or sodium.
